Mating Cues

AbstractThe evolution of new species is made easier when traits under divergent ecological selection are also mating cues. Such ecological mating cues are now considered more common than previously thought, but we still know little about the genetic changes underlying their evolution, or more generally about the genetic basis for assortative mating behaviors. The warning patterns of Heliconius melpomene and H. cydno are under disruptive selection due to increased predation of non-mimetic hybrids, and are used during mate recognition. We carried out a genome-wide quantitative trait locus (QTL) analysis of preference behaviors between these species and showed that divergent male preference has a simple genetic basis. Three QTLs each explain a large proportion of the differences in preference behavior observed between the parental species. Two of these QTLs are on chromosomes with major color pattern genes, including one that is tightly associated with the gene optix. Different loci influence different aspects of attraction, suggesting that behavioral isolation in Heliconius involves the evolution of independently segregating modules, similar to those for the corresponding wing pattern cues. Hybridization and subsequent sharing of wing pattern loci has played an important role during adaptation and speciation in Heliconius butterflies. The existence of large effect preference loci could similarly assist the evolution of novel behavioral phenotypes through recombination and introgression, and should facilitate rapid speciation.

Purpose People engage in green consumption for many reasons, both conscious and unconscious. This paper aims to draw on evolutionary psychology to propose that hard-wired mating strategies encourage both men and women to increase their green consumption in the presence of members of the opposite sex. Design/methodology/approach Observations were conducted on 324 students who purchased cold drinks in disposable cups from a college café. The students were offered the choice of adding 20 cents to their purchase for a bio-degradable cup. Findings Overall, 160 students agreed to pay the premium for a bio-degradable cup, with green purchases 46 per cent higher among women and 61 per cent higher among men when facing a cashier of the opposite sex. Originality/value The findings suggest that the activation of mating cues prompts students to display prosocial, altruistic behavior and/or to engage in conspicuous consumption (i.e. agreeing to pay more for the sustainable product). The study was conducted in the field using naïve participants and demonstrates the application of evolutionary psychology to green marketing. It also adds to what is a surprisingly small literature on the effect of employee–customer gender mismatch.

We describe a new species in the caddisfly genus Rhyacophila (Trichoptera: Rhyacophilidae) from the southern Cumberland Plateau of the United States.  Rhyacophila dandaganu n. sp. is placed in the Rhyacophila lobifera Group from North America, the second known species in this group.  The new species is distinguished from Rhyacophila lobifera Betten, 1934 by the shape and dimensions of several genitalic structures, as well as the absence of parameres accompanying the endotheca and the characteristic shape of the tenth segment and phallicata.  We discuss the geographic range of these two species and the questions raised by the curious (apparent) lack of sympatric populations.  We discuss some testable hypotheses that might determine how populations of R. dandaganu n. sp. and R. lobifera could maintain phenotypic distinctiveness, in the absence of obvious geographic barriers to gene flow, including behavioral, chemical or tactile mating cues.
